Valve Clearance
(cont’d)
Servicing Your Honda 53
Refer to
Sa
fety Precautions on page19.
Excessive valve clearance will cause noise and
eventual engine damage. Little or no clearance will
prevent the valve from
closing and cause valve
damage and power loss. Check the valve clearance
when the engine is cold at the intervals specified in
the Maintenance Schedule (page 21).
The checking or adjusting of the valve clearance
should be performed while the engine is cold.
The valve clearance will change as engine
temperature rises.
Before inspection, clean the engine thoroughly to
keep dirt from entering the engine.
